Mrs. Fields is celebrating its 40th anniversary on National Cookie Day by giving the first 400 fans at every location a free full-sized chocolate chip cookie. There will also be deals for up to 40 percent off certain packages on the website while supplies last.

First, you should head to your local Cinnabon ASAP and try their newest creation, the Cookie BonBite™. A list of locations offering the free cookie is available here.

Fun fact: According to a Nestle Toll House survey, when asked which cookie best describes the state they reside in, people in SC said peanut butter with chocolate chips. It's one of a plethora of "holidays" that exist primarily so businesses can promote themselves, but in this case, the Holiday Industrial Complex is serving up a bunch of free cookies, so maybe we shouldn't complain.

At Whole Foods, customers can get a full 50 percent off everything in the store's bar. The offer is only valid on December 4th and no purchase will be necessary.

This offer is for one free original chocolate chip cookie with no purchase necessary. The offer is good in USA stores only and only while supplies last.
